Dear all,

I have two different problems when trying to configure two-node a Cluster:

1. When starting the daemons (using cman startup script), ccsd says

  Cluster is not quorate.  Refusing connection.
  Error while processing connect: Connection refused

2. so I tried to modify the cluster configuration by Conga, but I
    received the following error message:

  The following errors occurred:
     * Node <hostname1> reports its cluster version is rhel4 and we
       expect rhel5
     * Node <hostname2> reports its cluster version is rhel4 and we
       expect rhel5

Both the nodes are running Scientific Linux 5.2 with kernel 
2.6.18-92.1.18.el5xen i686

the following rpm are installed:


I started configuring the cluster using the tool system-config-cluster.
I wanted a two-node cluster, using a quorum disk as 3rd vote. The quorum 
disk resides on a SAN connected via fiber channel. I inizialized it 
using 'mkqdisk ..." and both nodes can now correctly see it
   root# mkqdisk -L
   mkqdisk v0.5.2
         Magic:                eb7a62c2

This is the cluster.conf file:

root# cat /etc/cluster/cluster.conf
<?xml version="1.0" ?>
<cluster alias="sicr_vm" config_version="7" name="sicr_vm">
         <cman two_node="0" expected_votes="2"/>
         <quorumd label="CLUSTER_QDISK" interval="2" min_score="1" 
tko="10" votes="1">
                 <heuristic interval="2" program="ping -c 3 
<gateway_IP_address" score="1"/>
         <fence_daemon clean_start="0" post_fail_delay="0" 
                 <clusternode name="node1" nodeid="1" votes="1">
                 <clusternode name="node2" nodeid="2" votes="1">

Does anybody can help? I can'tfind where the mistake is...

Thank you,
